Abstract (en)
The improved silver halide color photographic material having as photographic constituent layers a blue-sensitive, a green-sensitive and a red-sensitive silver halide emulsion layer, as well as at least one non-light-sensitive hydrophilic colloidal layer on a support is characterized in that at least one of said photographic constituent layers contains at least one of the compounds reprecented by the following formula: <CHEM> (where R1 is a hydrogen atom or a monovaluent substituent; and R2 is a group having a Hammett's value sigma p of at least 0.2). This color photographic material is satisfactorily protected against deterioration in photographic performance such as reduced color or gamma, color contamination or increased fog even if it is exposed to formaldehyde and other deleterious gases for a long time of storage before it is subjected to color development and subsequent photographic processing.
